NAME
pmem2_errormsg() - returns last error message
SYNOPSIS
-
#include <libpmem2.h> const char *pmem2_errormsg(void);
DESCRIPTION
If an error is detected during the call to a libpmem2(7) function, the application may retrieve an error message describing the reason of the failure from pmem2_errormsg(). The error message buffer is thread-local; errors encountered in one thread do not affect its value in other threads. The buffer is never cleared by any library function; its content is significant only when the return value of the immediately preceding call to a libpmem2(7) function indicated an error. The application must not modify or free the error message string. Subsequent calls to other library functions may modify the previous message.
RETURN VALUE
The pmem2_errormsg() function returns a pointer to a static buffer containing the last error message logged for the current thread. If errno was set, the error message may include a description of the corresponding error code as returned by strerror(3).
